I received an email from Sophie Schlingemann, the IPCC Legal and Outreach Officer, requesting removal of the Zero Order Drafts from my site. The wording is nearly identical to the letter received by Gallopingcamel. I believe these documents are of public and journalistic interest, and that I have a right to publish them, and plan to decline.
Also, I've put up a Zipped file (71 MB) of all the ZOD documents here, and an RAR-compressed file (77 MB) here. The latter is also mirrored at Cryptome.
